Square stance, open hips

[bunkerputt]

I'm experimenting a little bit with a slightly different address setup.  I set my feet in line with the target, but I open my hips some, and open my shoulders less.  This creates a little bit of torque at address.  Then, when I make my shoulder turn, the hips get pulled back more naturally, since a lot of the slack between the shoulders and hips is taken out.  I can maintain the feeling of tension between them throughout the entire swing much more easily and it feels like a much simpler motion.  It also takes a lot of the pressure off my lower back on the downswing.  Does anyone setup like this or can you point me to some good info on it?
